CHURN.

SPECIFICATION formingpart of Letters Patent No. 770,401, dated September20, 1904.

Application filed January 28, 1904. Serial No. 191,051. (No model.)

To ctZZ whom it may concern.-

Be it known that I, HENRY A. THoMAssoN, a citizen of the United States,residing at Whatcorn, in the county of Whatcom and State of VVashirgton,have invented a new and useful Churn, of which the following is aspecification.

This invention relates to certain improvements in churns, and moreparticularly to that class commonly known as working body churns.

One object of the invention is to provide a simple, inexpensive, andefficient device of this character capable of being easily operated andby means of which large quantities of milk or cream may be quicklychurned in independent vessels driven from a common operating-shaft.

A further object of the invention is to provide a crankedsupporting-shaft having a plurality of churn boxes or casings mountedthereon and spaced at uniform angular distances, so as to counterbalanceeach other, said churnboxes being detachably mounted on the shaft topermit the same to be quickly removed when desired.

A still further object is to provide a coupling-bar adapted to connectthe respective cranks of the operating-shafts when one or more of thechurn-boxes are removed, said bar being provided with a series ofremovable weights adapted to counterbalance the remaining box or boxes.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended, itbeing understood that various changes in form, proportion, and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of this invention.

In the accompanying drawings, Figure 1 is a perspective view of a churnconstructed in accordance with my invention. Fig. 2 is a longitudinalsectional view of the same. Fig. 3 is a top plan view showing two of thechurncasings detached from the crank-shafts and the weightedconnecting-bars secured in position 5 thereon. Fig. 4 is a transversesectional view of the connecting-bar, and Fig. 5 is a detail perspectiveview of the same.

Similar numerals of reference indicate corresponding parts in all thefigures of the draw- 5 5 ings.

1 designates the frame of the churn, comprising the end beams 2 andlongitudinal bars 3, to which are secured in any suitable manneruprights 4. Journaled in bearings 5 in the longitudinal bars 3 aresupporting-shafts 6, the cranks 7 of which are angularly disposed withrelation to each other and form hangers or supports for churn boxes orcasings 8. The churn-boxes 8, which may be of 5 any desired shape, arepreferably rectangular in contour, as shown, and provided each with acentral opening or orifice 9, through which the milk or cream isintroduced, the fillingorifices being closed by suitable lids or covers7 10. Secured to the opposite ends of the churn-boxes 8 and at the loweredge thereof are outwardly-extending ears or lugs 11, to which arepivoted in any suitable manner bearing-plates 12, provided with bearings13, in which are journaled the crank-arms 14 of the cranks 7.

The bearing-plates 12 are provided with threaded openings 15, adapted toreceive securing-bolts 16, which engage threaded lugs 30 17, secured tothe top of the churn-boxes and by means of which said boxes aredetachably supported on their respective cranks or hangers, as clearlyshown in Fig. 1 of the drawings.

The crank-shafts 6 are secured in the bear- 5 ings 5 by longitudinalretaining-strips l8, fastened in any suitable manner to the beams 2, andthe terminal portion of one of said shafts is preferably bent to form acrank or handle, as shown at 19. The relative disposition of 9 thesupporting-shafts is such that when the churn-boxes are secured inposition thereon one box will counterbalance the other, therebyequalizing the draft and rendering the churn easy of operation.

As a means for balancing the machine when but a single churn-box isemployed I provide a coupling-bar 20, the opposite ends of which byrapidly and effectively churned.

are provided with hinged members 21, havl ing bearings 22 formed thereinadapted to receive the crank-arms 1 L, said bars being secured inposition on the crank-arms by clamping-screws 23. Slidably mounted onthe coupling-bar 20 are a series of removable Weights 24:, each providedWith a clampingscrew 25, which engages the bar and prevents accidentaldisplacement of said Weights as the churn-boxes are rotated.

In operation the milk or cream is introduced in the diflerentchurn-boxes through the filling-orifices 9, after Which the lidslO areclosed and the boxes rapidly rotated by turning the handle 19, Whichcauses the milk or cream to he violently agitated, and there- VVhen itis desired to operate but a single churn-box, the side boxes are removedand the crank-arms 14: of the shafts 6 connected by the coupling-bar 20,the number of Weights employed being in proportion to the amount of milkor cream being churned in the central box.

It is obvious the churn-boxes may be provided with one or more dashersor breakers, if desired, and the machine instead of being operatedmanually may be operated from any suitable source of power.

Having thus described the invention, What is claimed is 1. A device ofthe class described comprising supporting-shafts each having a pluralityof equidistantly-spaced cranks, and a plurality of churn-boxes mountedon said cranks and arranged to counterbalance each other.

2. A device of the class described comprising a pair ofsupporting-shafts each having a plurality of equidistantlyspaced cranks,a plurality of churn-boxes detachably secured to said cranks, and meansfor counterbalancing said boxes.

3. A device of the class described comprising a frame, a pair of crankedshafts journaled in the frame, a plurality of churn-boxes removablymounted on the shafts, and a rod or bar provided With removablecounterbalancing-Weights adapted to connect said shafts.

4;. A device of the class described comprising a frame, a pair ofcranked shafts journaled in the frame, a plurality of churn-boxesprovided With pivoted bearing-brackets adapted to receive the shafts,said boxes being spaced at uniform distances to counterbalance eachother, and means for locking the bearing-plates in engagement With saidshafts.

5. A device of the class described comprising a frame, a pair of crankedshafts journaled therein, a plurality of churn-boxes removably mountedon said shafts, a coupling bar or rod provided With hinged lockingmembers adapted to connect the shafts, removablecounterbalancing-weights carried by the rod or bar, and means forclamping the Weights in position thereon.

In testimony that I claim the foregoing as my oWn I have hereto affixedmy signature in the presence of two Witnesses.

HENRY A. THOMASSON.
